    Boil Steam
AI Thread Summary
To determine the required mass flow rate of steam for melting 100 kg/h of plastic, it's essential to first calculate the heat needed based on the thermal properties of the specific plastic being used. Understanding the specific heat capacity and melting point of the plastic will help in estimating the total energy required. Once the heat requirement is established, the appropriate boiler can be selected to match the steam output needed for the process. The discussion emphasizes the importance of knowing the thermal properties of the material to make accurate calculations. Proper calculations will ensure efficient melting of the plastic using steam.

Hi there,

I am working on a process in which I have to melt 100 kg/h of plastic. The best way we thought of doing this was to use a boiler (steam generator) to produce sufficient heat to boil the plastics in time. I am currently trying to choose the right boiler for the system. Yet, I do not know how to calculate the required mass flow rate of steam to boil the mass flow rate of the incoming plastics. Can anyone give me an equation, or explain how I can calculate this?


Thanks!

First you need to know how much heat you need. Do you know the thermal properties of your plastic?
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
